AUTOMATIC FIREARM. I

. No: 853,438. Specification of Application filed Augnst1B,1905. SerialNo. 274,689.

1b all; whom it may concern.- Be it known that I, JOHN-M. BROWNING, acitizen ofthe United States, and a resident of I thecity of Ogden, inthe county of Weber and State of Utah, have invented certain new anduseful Improvements in Automatic Firearms, of which the followingis aspecification, reference bein had to the accompan ing drawing, formingapart hereof.

Tliisinvent'ion relates to automatic firearms such, for instance, as areshown and described in Letters Patent of the United States No. 659,786,issued to me October 16, 1900;, an'd'the general object of the inventionis to improve in certain particulars the arm shown and described. insaid LettersPatent, although the improvements are capable .of beingapplied to other firearms of like gen eral character. 4 v

The invention concerns the taking down of the gun. In doing this, thehandle upon the bolt mechanism by means of which the gun is manuallyopened and which handle Works in a slot *in the receiver, has to beremoved before the bolt and its associatedparts' can be pushed outfromthe forward end of the receiver; Thisv handle therefore, inaccordance with the present invention, is fastened to the bolt mechanismin such a way as to be readily attached and detached as. required.

Theinvention will be more fully described with reference to theaccompanying drawing in which the improvements are illustrated in .aconvenient and practical embodiment. g

- In said drawing: Figure l-is a view in side elevation of-an arm towhich the improvementmay be ap' lied; Figs. 2 and 3 are sectional viewsof t e bolt carrier, Fig. 2 showing thehandle and its parts in'section,and Fig. '3 showing the handle in elevation;- Figs. 4 and 5 arerespectively an'end view and a; view in side elevation of the handle;FFig. 6 is a view in front elevation of the bolt mechanism 'Figs. 7 andSare respectively'a top view and a side 'view' of the nut in'the handleand Figs. 9 and 10 are res ectively a View in. elevation of the springan a view in .elevation of the pin in the handle.

. The'bolt mechanism, as in' the Letters Pat- 3 whichmoves backward inthe receiver 6 together with the barrel upon-each recoil, and then movesforward again and closes. the breech. During this operationthe h'andle 2.by the carrier may then be pushed forward upon the. carrier works in -aslot 7 as will be:

obvious from Fig. '1 and as has already been described injsaid LettersPatent. 7

In accordance with the present invention, the handle and carrier are.formedwith a sliding connection such as a dove-tail connec- Ttion,whereby the handle, when the gun is to.

be taken apart, may beslid out from the carrier and removed fromthecarrier and whereout of the receiver. In the present case, the 6 handleis shownto haves T shaped portion arand the carrier a corres ondinglyshaped groove in which this T-sihaped portion is adapted to slide. Inorder to secure the handle within the groove in the carrier in I such away that it may be readily attached and detached therefrom, 'means suchas a pin '1) extendin through the handle so as to be accessible from theexterior thereofis provided. This pin is ada ted to engage a re- '7 5cess c in the carrier an thereby to hold the handlefirmly Within thegroove in the carrier.

. In order to keep the pin 5 in the recess 0,

any suitable means may be emplo ed, such,

for instance, as a spring (1, one on of which maya'but against theshoulder e upon the pin while the other end-of which rests against a nutf threaded in the endbf the handle. In this way the in-is normally heldin its recess and ma be quickly and easily re- .Inoved' by the' ger. Ifdesired, a grooveg may be provided upon theouterend of the piri in orderthatthe end of the pin may be the more conveniently grasped.

- Various changes in the construction shown and described herein may be'made without departing from the spirit of the invention,

and the .improvementsare not limited therefore to the present embodimentthereof.

Furthermore, as was stated at the outset, the improvements arenot'limited' in .a plication to the gun mechanism shown an described inthe present case nor to the mechanism shown and described inthe LettersPatent above referred to. rco

I claim as my invention 1 1. In afire arm, the combination with thereceiver and breech mechanism, of a handle detachablysecured to the'said mechanism in a-slot in the receiver, anduc 5 means in t e handlevwher'eb the handle may be secured to and detached from the boltmechanism.

'2. In a fire arm, the combination with the receiver and breech boltmechanism, of a 1'10 receiVer and breech bolt mechanism, of a handle formoving said mechanism, said handle working in a slot in the receiver andhaving a sliding connection with the bolt mechanism, and a gspringactuated pin adapted to fasten the handle to the bolt mechanism andaccessible from the exterior of the handle whereby thehandle may besecured to and detached from the bolt mechanism.

4. In a fire arm, the combination with the receiver, breech'bolt andbreech bolt carrier, of a handle having a sliding connection with thecarrier and working in a slot in the receiver, a pin extending throughthe handle and adapted to enga e a recess in the carrier to lock thehandle t ereto, and a spring to. hold the pin normally inthe recess.

This specification. signed and witnessed this 14th day of August, 1905.
